Of the 10 accused who were chargesheeted by CBI in the case, four are at present out on bail.

Accused Rahul Yadav, Samir Sandhir and Sushil Daga were granted bail by the court on August 12 on a personal bond of Rs 5 lakh with two sureties each of the like amount even though CBI had opposed it.

Alleged middleman Ajay Garg, who has been accused of being instrumental in fixing the bribe amount for getting a lucrative post for Kumar, was granted bail by the court on July 8.

CBI, in its chargesheet filed on July 2, has alleged that Singla had demanded Rs 10 crore from Mahesh Kumar for his appointment as member (electrical).

The probe agency has said it was decided between the accused that Rs 5 crore would be paid before the appointment and rest of the money will be paid after the job was done.

The first tranche of Rs 89.68 lakh was given to Singla who was apprehended while accepting the money, it has said.

All 10 accused have been chargesheeted for the offence of criminal conspiracy under the IPC and relevant provisions of the Prevention of Corruption Act.

Former minister Bansal, who resigned from the Union Cabinet in the wake of the scandal, has been named as one of the key witnesses in the case while his nephew Singla has been termed as the "main person" whose influence was to be allegedly used for getting Kumar appointed to the post.
